TO ALL WHOM IT MAY CONCERN: t h

YBe it known that I, DEXTER SMITH, of Springfield, Hampden county,Commonwealth of Massachusetts, have invented certain new and usefulimprovements in Machines for Heading and Cutting off Metallic CartridgeGases; and do hereby declare that the following is a full and exactdescription of the same, reference beinghad to the accompanying drawingsand tothe letters of reference marked thereon. i My improvements consistin combining the operation of trimming the shell to the required length,andthe operation of heading the same in one machine and transferring theshell from the mechanism for trimming to` the mechanism for headingautomatically by means of devices which Iwill hereafter describe; also,in a peculiar arrangement of mechanism for operating `the cutting-oli'tool, and in an improved chuck for holding and revolving Vthe shellwhile it is being cut off. These improvements are shown in the drawingswhich accompany these specifications, in which- Figure I is a plan viewof my improved machine.

Figure 2 is a perspective view of the same.

Figures 3, 4, and 8 are detailed views of the chuck.

Figure 5, a side view of the device for stopping the disk.

Figures 7 and 6, views of the shell after and before heading. p f

A is the bed of the machine, to whichthe other parts are attached. B isthe shaft to which power is applied at C, and from which the movingparts derive motion by means of suitable connections. At the oppo` siteend of the bed from the shaft, B, and supported by suitable bearings, Iplace `the shaft, D, to which are attached the arms, E F` G. Motion isgiven to this shaft from the cam, H, on the shaft, B, by means of thcconnection, I, supported by the lever, J, and" the sliders, K L, areoperatedby means of connections, M N, pivoted to them and to the arms, EF. The slide, K, carries at one end a punch or mandrel, S, and worksthrough the piece,ib, which has a slot, c, formed in it, into which thecartridge ca'se is dropped, andthe punch, S, coming forward carries thecase along into the chuck, O, which is of Va peculiar construction, andwill be more fully described hereafter. After it is inserted in thischuck, it is revolved by power` applied at the pulley, d, and the tool,Z, being forc'ed up by the lever, X, operated from the shaft, B, bythecam, Y, chts or trims off the shell, thus forming itof the desiredlength. After this is done, the mandrel, S, is withdrawn and forcesanother" shell in by a series of movements similar to that justdescribed, and the previously inserted shell is pushed out` h throughthe centre of the pulley, d, and intoa hole in the disk, P. This disk isnow partially revolved byi` means of the rat'chet,vg, and pawl, h,operated by Athe cam, K, by means of suitableconnections, and is stoppedby means of the catch-pisode,springing-into notches 1, 2,3, Snc., in theedge of the disk, P. `Just before' motion is given to the disk thiscatch-piece is thrown out of the notch by means of the lever, y, underthe bed h of the machine, operated by the cam, 0. After the disk P hasbeen revolved far enough to carry the shell iirst h i trimmed aroundopposite the punch, R, it and'each successive shell are forced into thedie, S, by this punch, R, operated from the shaft, D, by means of thearm, F, and connection, n, and the-heading-punch, T, is forced upagainst the closed end of the shell from the oppositeside, operated fromthe shaft, by means of the'cam, p,

and the head or rim, a, is formed, leaving `the shell in the shape shownin fig. 7,`readyifor filling.` The mandrel, S, is constructed in' apeculiar manner, having at its end a collar, c, which entersthe shell,and which part alone 1 revolves, and not the whole of the mandrel, asscommonly the case. The construction of the chuck, O, now

remains to be described. This is shown in the drawings, at figs. v3 and4; g. 3 being a face view of thc chuck i i l with the cover removed, andfig; 4 being a cross-section through the same. It consists of twopieces, U', i inserted in a slot in the body of the chuck,'and having ahole in the centre for the insertion of the cartridge;

these pieces, U are kept together by means of springs, W, on one or bothsides, the tension pf which isgoverned by the set-screws, a: fr', sothat when a shell is pressed into the opening in the chuck it is `held`there by the pressure of the springs, thus allowing for slightvariations in the shells'. I insert the die, j, in the face, as shown iniig.` 8, for the purpose of guiding and centring the shell in itsentrance into the chuck.

Iam aware that machines have been made in which these operations I havedescribedl have been performed,A

but never, to my knowledge, have they been combined so as to workautomatically together, taking the shell in the form shown in fig. 6,and leaving it in the form shown in iig. 7. This Ihavc accomplished bythc arrangement of the machine, and by placing the disk, P, as' shown,and operating it to transfer the shells fromonc side to the other, asIhave described and in this, and the peculiarities of construction Ihave described, my improveh ments consist. lso, in thepcculiararrangement of the mandreLS, with the devices for operating it inconnection with the tool, Z, and devices for operating that, I have agreat improvement, for the cani, H, isan eccentric; and `when the part,z', of the connection which Works'in the groove in the side is nearestthe centre, and while the cam is moving, the mandrel is stationary, andthe tool, Z, is so arranged that at just this' time it is forced up bythe cam, Yand cuts the shell while the longitudinal motion of themandrel is stopped. This being done, the cutting-tool is immediatelywithdrawn and the motion of the mandrel recommenees. do not wish toconfine myself` to any particular device for transferring the shell fromone side of the machine to the other, as instead of the disk, P, I canuse a. slide or oscillating arm.

Now, having described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. 'I claim the Adisk P, operated from the shaft B by means of the camsK and O, connected with the ratchet and pawls gJL, and stop-piecem, orequivalent mechanism for the purpose of transferring'the shells,substantially as herein set forth. i

2. The combination of the cam H, shaft D, and mandrel S with the camYand tool Z, when arranged and operating substantially and for thepurpose as described.

3. The chuck O, constructed as described and used for the purpose ofholding the shells, as set forth.
